Well I tried my first mod. I did the one for the carts. I believe its called the plug mod? Anyway I took out the batting from a cart. Dripped some liquid in the empty cart up to the ledge part. I just eyed this part. Looked at the batting as 3 parts and cut 1/3 of it. Put batting back on top and works like a champ. No leakage and I can also taste the liquid better. Im loving the RY4. This was the easiest mod I could find. Im happy with it.
